convergence insufficiency treatment trial protocol

U.S. Department of Health and Human Services, The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Due to sample size considerations, it was not feasible to compare the HB-PU group with the HB-P group as a primary outcome pairwise comparison based on the assumed successful outcome percentages of 15% vs. 10%. The Convergence Insufficiency Treatment Trial (CITT) is a prospective, masked, placebo-controlled, multi-center clinical trial in which 208 subjects between the ages of 9 to < 18 years will be randomly assigned to: 1) Home-based Pencil Push-Up Therapy, 2) Home-based Pencil Push-ups with Computer Vision Therapy/Orthoptics, 3) Office-based Vision Therapy/Orthoptics, or 4) Placebo Office-based Vision … He accepts all insurances and Medicaid. The number of subjects classified as a success based on clinical measures of CI (mean NPC break & mean PFV blur) at the 6-week visit. 2016 Dec;93(12):1457-1465. Placebo computer-based therapy will be provided by the Home Therapy System (HTS) computer software. Harrison RL. Table of Contents . At that time the group used the acronym CIRS (Convergence Insufficiency Reading Study). The Convergence Insufficiency Treatment Trial–Attention & Reading Trial (CITT-ART) was a multicenter, double-masked, randomized clinical trial designed to determine if office-based vergence/accommodative therapy resulted in improvements in reading 16 and attention in 9- to 14-year-old children with symptomatic convergence insufficiency. The baseline data reported herein define the clinical profile of those enrolled into the CITT. Convergence Insufficiency Treatment Trial (CITT) Investigator Group. 2008; 15(1):24-36 (ISSN: 1744-5086). This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children. Astigmatism cylinder must be within 0.50D of full correction and axis must be within 5 degrees. PMID 18852411 6. Outcome data on the Convergence Insufficiency Symptom Survey (CISS) score (primary outcome), near point of convergence (NPC), and positive fusional vergence were collected after 12 weeks of active treatment and again at 6 and 12 months posttreatment. We also report the clinical and demographic characteristics of patients. Main Outcome Measures: Convergence Insuffi-ciency Symptom Survey score after 12 weeks of treat-ment. reinforcement (OBPT) as treatments for symptomatic convergence insufficiency (CI). doi: 10.1002/14651858.CD006768.pub3. Relocation outside of area of an active PEDIG site within the next 15 months is not anticipated. Scheiman M, Kulp MT, Cotter SA, Lawrenson JG, Wang L, Li T. Interventions for convergence insufficiency: a network meta-analysis. We also report the clinical and demographic characteristics of patients.We prospectively randomized children 9 to 17 years of age to one of four treatment groups: 1) … Optom Vis Sci. To be considered an overall success, each of the following criteria must be met for the 3 outcome measures at 6 weeks: (Note: All 3 criteria must be met in order to be classified as an overall success at the 6-week visit). Methods. Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children. N2 - Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children. Vergence Eye Movements. have attention problems during reading tasks and that the successful treatment of symptomatic CI can lead to improved attention during reading. A recently completed randomized clinical trial, the Convergence Insufficiency Treatment Trial (CITT), demonstrated that a 12-week program of office-based vergence/ accommodative therapy with home reinforcement was more effective than home-based near target pencil push-ups, home-based computer accommodative therapy plus pencil push-ups, or office-based placebo therapy in treating the symptoms and signs associated with symptomatic CI in children 9 to 17 years of age. COVID-19 is an emerging, rapidly evolving situation. The number of subjects who are classified as a success based on the mean PFV blur at the 12-week visit. Many clinicians believe that the less costly and less complex treatment option should be attempted first. I read the article by Scheiman et al 1 entitled “A Randomized Clinical Trial of Treatments for Convergence Insufficiency in Children” in the January 2005 issue of the A RCHIVES with great interest. Parent has home phone (or access to phone) and is willing to be contacted by Jaeb Center staff. For hyperopia, the spherical component can be reduced by up to 1.50D at investigator discretion provided the reduction is symmetrical and results in residual (i.e., uncorrected) SE hyperopia that does not exceed +2.00D. Gallaway was also the Principal Investigator at Salus University for the Convergence Insufficiency Treatment Trial (CITT), an NIH funded randomized multicenter clinical trial … The assumed success percentages were determined based on the Convergence Insufficiency Treatment Trial (CITT) 14 and clinical expertise. Previous CITT Study. •Surgical Care: Eye muscle surgery should only be considered with a licensed eye care specialist’s recommendation (Cooper, 2001 -2005). Astigmatism > 1.00D or > 1.50D of meridional difference in either eye Refractive correction for patients meeting the above refractive error criteria must meet the following guidelines: SE anisometropia must be within 0.25D of the full anisometropic correction. reinforcement (OBPT) as treatments for symptomatic convergence insufficiency (CI). Vision therapy for CI is based upon the protocol set by the Convergence Insufficiency Treatment Trial (CITT), and consists of office-based vergence/accommodative therapy with home reinforcement. To evaluate the kinetics of change in symptoms and signs of convergence insufficiency (CI) during 12 weeks of treatment with commonly prescribed vision therapy/orthoptic treatment regimens. This procedure utilizes a 4 pd base right/4 pd base left prism flipper and "Accommodative Hopping Cards". The NEI Convergence Insufficiency Treatment Trial (CITT) has shown that the most effective treatment for CI is in-office therapy, overseen by a trained therapist, with additional at-home exercises. Home-Based Therapy for Symptomatic Convergence Insufficiency in Children: A Randomized Clinical Trial. Researchers evaluated the accommodative function of patients with symptomatic convergence insufficiency and coexisting accommodative dysfunction who underwent vergence/accommodative therapy. Main Outcome Measures—Convergence Insufficiency Symptom Survey (CISS) score after 12 weeks of treatment. Although home-based therapy using computer software is becoming more popular, no prospective data are available to demonstrate the effectiveness of home-based vision therapy using computer software compared to home-based near target push-ups or home-based placebo computer therapy.
